Block structured mesh issues!!!
Could someone tell me the problems with using a rectangular mesh in flow simulator. I am modelling the airflow around an s809 aerofoil and beleive that because my boundary cuts through alot of the cells im loosing detail around the boundary layer. Is this true and are there other issues i should be worried about----
please could you send me the prequel reading thanks. i hve already attempted to read this before and to no avail
here you go.
Hi Ariel, could you elaborate on exactly what the problem is? It sounds like you're getting results you aren't expecting and you think that is because of the meshing at the boundary of fluid and solid. If that is the case, I would recommend you also take a look at the technical reference, solving engineering problems doc, the forum and also the solidworks KB. The software can handle the case that you are describing and if you've done a good job of meshing at the boundary will get you decent results and you shouldn't concern yourself too much about exactly the formulation that the software is using. Trust it, check the validation problem, and then let us know what you're comparing your results to and what your expectations are. You may also want to post some pictures of your model, describe your setup and show us your mesh.
.This file discusses the B'layer and tuurb modeling. There is another similar one about hte meshing scheme whichs likely required reading before you understand this one, assuming you don't understand the "immersed boundary" scheme. If that is true let me know and I will post the other one. It is also about 5MB or so.
